The Wire - January 2006: "Jacob Kirkegaard is not so much a composer as a sound hunter - a man on a quest to capture sonic ineffabilities and bring them to our ears. In the past he has used his collection of probes, accelerometers and contact microphones to record the interior noise of ice crystals and the tiny transformative cries of nuclear fission. On Eldfjall (which translates as 'Fire Mountain') he offers an insight into the restlessness of the Earth's core by documenting the geothermal vibrations of Iceland's volcanic geyser regions. Given that they were made in such a tumultuous landscape, it's no surprise that these recordings are wonderfully and fascinatingly various - an utterly inhuman, but strangely immersive array of hisses, slithers, drones and swirls whose cumulative impact far surpasses that of many human contrivances."
